Hi, I connected my synth to my computer and wanted to use it's sound because they are better than the ones on my computer. I connected it via usb cable and was able to play the notes but when I wanted to use the sounds of the synth I played the notes and they didn't make a sound. I know the computer is receiving the messeges because if I put record it does record the notes, and plus when I'm using a software computer instrument it also plays the notes. What could be the problem here? I already put the synth in the midi setup and when I created the track I specified that I wanted the sounds of the Yamaha MO8. What could be the problem? I'm using Logic Pro. thanks!
